I can suggest a somewhat different approach. You may execute this
command in the terminal (requires ImageMagick, which is rather
ubiquitous):

sleep 3 && import -window root output.png

which will grab the entire screen after 3 seconds and save the image
into 'output.png'. This way you can open any menu and choose any
element of the menu _before_ the 'import' command gets executed.

You could also play with parameters a bit. For example, you could
extend the waiting time if you need. You could also redirect the output
to the 'display' command (also from ImageMagick) in order to check the
screenshot out before saving it to file (it is possible to save file
from the 'display''s menu):

sleep 3 && import -window root - | display

So, this is not exactly what you asked (no control via hotkeys),
however, the task of assigning the hotkeys may be solved separately.
For example, the XFCE and JWM desktops (as well as virtually any
desktop environment out there) let one assign the custom hotkeys for
any commands. So it is easy to link the commands I suggested above to
any hotkeys you want. I use it in JWM a lot.

I hope, my suggestion is useful.
